The initial step of a DWH provider is to create a personalized data warehouse structure for its clients. This is done by analyzing their distinctive business needs, current data management tactics, data origins, and quality measures. After finalizing the framework and ensuring its ability to adapt to future requirements, the provider moves on to the implementation phase. It involves carefully selecting appropriate hardware, software, and procedures to complement the custom design.
Once the custom data warehouse has been configured, the provider amalgamates it with all current data sources, including the customer's transactional systems. Depending on the circumstances, the approach may involve utilizing cutting-edge pipeline technologies or customized code to guarantee secure data transmission to the warehouse. Additionally, certain providers interlace the warehouse with present analytical solutions for internal analytics.
After the data sources have been integrated, the information they contain is combined, purified, enhanced, and consistently evaluated to ensure its conformity with the core data model. The purified data is then transmitted to the customer's chosen cloud platform. However, certain providers also allow for hybrid approaches where some data is retained on the customer's premises while the rest is stored in the cloud.
After the warehouse is established, the provider manages the upkeep of data accuracy, addition and removal of sources, and periodic checks on performance and ETL correctness. The provider guarantees that all aspects of the service, including the data model and infrastructure, comply with privacy, security, and governance standards.
After the warehouse is activated, the service provider performs the duty of maintaining data quality, managing sources, verifying performance, and periodically ensuring the extract, transform, and load (ETL) process's accuracy. The provider also ensures that the entire service adheres to privacy, security, and governance standards, from the data model to the infrastructure.
